Tool Accuracy Checkers

Calibration Rods with Calibration Certificate

The included certificate of calibration traceable to NIST states that these rods have passed a test for accuracy.

Calibration Rods

Also known as calibration standards, these rods let you check and set micrometers and other measuring tools.

Micrometer Check Gauges

Check for out-of-parallel anvils and determine wear on micrometers.

Gauge Blocks

Vital for dimensional quality control, these gauge blocks are often used for precision layout, machine setup, and producing close-tolerance dies and fixtures.

Mitutoyo Gauge Block Sets with Calibration Certificate

These sets come with a certificate of calibration traceable to NIST that states they’ve passed a test for accuracy.

Mitutoyo Gauge Block Sets

Use these Mitutoyo gauge block sets for precision layout, machine setup, and producing close-tolerance dies and fixtures.

Economy Gauge Block Sets

Use these gauge block sets for precision layout, machine setup, and producing close-tolerance dies and fixtures.

Starrett Gauge Block Sets

Use these Starrett gauge block sets for precision layout, machine setup, and producing close-tolerance dies and fixtures.

Angle Block Sets

Create and check angles with these precision-ground blocks. Each block is labeled with its angle.

Setup Blocks

Use these tight-tolerance blocks as mounting bases and supports to ensure accurate angles and spacing.
